Examining the quality of knowledge transfers – the draft of an empirical research

Already successfully used products or designs, past projects or our own experiences can be the basis for the development of new products. As reference products or existing knowledge, it is reused in the development process and across generations of products. Since further, products are developed in cooperation, the development of new product generations is characterized by knowledge-intensive processes in which information and knowledge are exchanged between different kinds of knowledge carriers. The particular knowledge transfer here describes the identification of knowledge, its transmission from the knowledge carrier to the knowledge receiver, and its application by the knowledge receiver, which includes embodied knowledge of physical products. Initial empirical findings of the quantitative effects regarding the speed of knowledge transfers already have been examined. However, the factors influencing the quality of knowledge transfer to increase the efficiency and effectiveness of knowledge transfer in product development have not yet been examined empirically. Therefore, this paper prepares an experimental setting for the empirical investigation of the quality of knowledge transfers

Design of Strongly Modulating Pulses to Implement Precise Effective Hamiltonians for Quantum Information Processing

We describe a method for improving coherent control through the use of detailed knowledge of the system's Hamiltonian. Precise unitary transformations were obtained by strongly modulating the system's dynamics to average out unwanted evolution. With the aid of numerical search methods, pulsed irradiation schemes are obtained that perform accurate, arbitrary, selective gates on multi-qubit systems. Compared to low power selective pulses, which cannot average out all unwanted evolution, these pulses are substantially shorter in time, thereby reducing the effects of relaxation. Liquid-state NMR techniques on homonuclear spin systems are used to demonstrate the accuracy of these gates both in simulation and experiment. Simulations of the coherent evolution of a 3-qubit system show that the control sequences faithfully implement the unitary operations, typically yielding gate fidelities on the order of 0.999 and, for some sequences, up to 0.9997. The experimentally determined density matrices resulting from the application of different control sequences on a 3-spin system have overlaps of up to 0.99 with the expected states, confirming the quality of the experimental implementation.Comment: RevTeX3, 11 pages including 2 tables and 5 figures; Journal of Chemical Physics, in pres

Experimental ionization of atomic hydrogen with few-cycle pulses

We present the first experimental data on strong-field ionization of atomic hydrogen by few-cycle laser pulses. We obtain quantitative agreement at the 10% level between the data and an {\it ab initio} simulation over a wide range of laser intensities and electron energies

Ready or Not, Here They Come: Acting Interns’ Experience and Perceived Competency Performing Basic Medical Procedures

OBJECTIVE: To assess acting interns’ (AI’s) experience with and perceived level of competency performing 6 basic medical procedures. DESIGN: Fourth-year medical students at the University of Cincinnati (UCCOM) are required to complete 2 AI rotations in Internal Medicine. All AIs in 2003–2004 (n = 150) and 2004–2005 (n = 151) were asked to complete a survey about whether during each of their rotations they had performed and felt competent performing the following procedures: phlebotomy, intravenous (IV) catheter insertion, arterial blood gas (ABG), nasogastric (NG) tube insertion, lumbar puncture (LP), and Foley catheter insertion. RESULTS: Four hundred sixty-seven of 601 possible surveys (across both years and both rotations) were completed (78% response rate). During both rotations, relatively few students performed the procedures, ranging from 9% for Foley catheter insertion (24/208) to 50% for both ABG and NG tube insertion (130/259). The two procedures most often performed were ABG (range 46–50%) and NG tube insertion (range 42–50%). Feelings of competency varied from 12% (LP) to 82% (Foley catheter). Except for LP, if students performed a procedure at least once, they reported feeling more competent (range 85% for ABG to 96% for Foley catheter insertion). Among the students who performed LP during a rotation, many still did not feel competent performing LPs: 23 (74%) in rotation 1 and 20 (40%) in rotation 2. CONCLUSION: Many fourth-year students at UCCOM do not perform basic procedures during their acting internship rotations. Procedural performance correlates with feelings of competency. Lumbar puncture competency may be too ambitious a goal for medical students

Evaluation of best practices for landrace conservation: farmer evaluation

Traditional farming systems and conservation of local cultivars and associated indigenous knowledge are under threat and growing pressure resulting in genetic erosion of crop diversity. These systems are an essential component of sustainable crop production, household income and human nutrition for many of the poor farmers found in fragile semi-arid ecosystems of sub-Saharan Africa (SSA). With the signing of the Convention on Biological Diversity (CBD) in 1992, in situ conservation for crops and their related genetic resources has been given prominent mention in global and national policies for biodiversity conservation. In situ strategies are an important and complementary component of the overall agrobiodiversity conservation efforts that aim to conserve not only crop genetic resources but also crop evolutionary processes. However, policy support of the science and practice of in situ conservation, lag behind CBD commitment in much of SSA. The need for activities on in situ conservation of plant genetic resources is emphasized in the CBD and in Agenda 21. Article 2 of the Convention specifically includes reference to domesticated or cultivated species. This is also anticipated in Article 8, which requires signatory Nations to “preserve and maintain knowledge, innovations and practices of indigenous and local communities embodying traditional lifestyles relevant for the conservation and sustainable use of biological diversity …” Agenda 21 reflects this commitment to in situ conservation as an essential component of sustainable agriculture, and in Chapter 14, notes the need for establishing programmes and policies to strengthen in situ conservation. In its second meeting, the Conference of the Parties to the CBD (COP 2) identified implementation of Article 8 of the CBD as a high priority and reaffirmed the importance of regional and international cooperation for the implementation of this Article. It also stressed the importance of the exchange of relevant information and experience among all stakeholders on measures taken for its implementation (Decision II/7 of COP 2). Many national PGR programmes in SSA are unable to meet their obligations towards in situ (more specifically on-farm) conservation as stated in the CBD and the Global Plan of Action (GPA) because of ineffective enabling of national policy environments that do not support traditional farming systems and in situ conservation on-farm. In order to strengthen the capacity of countries to implement effective policy, Bioversity International and national programme partners developed a project on “Community-based management of plant genetic resources in arid and semi-arid areas of Africa” funded by the Global Environment Facility (GEF) through the United Nations Environment Programme UNEP). The countries involved in the project were Benin, Burkina Faso, Ghana, Kenya, Malawi, Mali, Uganda and Zimbabwe. Through case studies, the project analysed farming systems in semi-arid ecosystems in these countries, focussing on how these systems supported the conservation of landraces of local and global significance. The methodology described in the present publication was designed within this project to draw out ‘best’ practices on how landraces have been incorporated into farming systems and/or national agricultural policies and biodiversity conservation strategies. On one hand, the farmer or resource user determines what makes the practice the ‘best one’, and they base their choices on a survival strategy or utilitarian point of view. On the other hand, the scientists on the project primarily judged how effective the practices are in conserving agrobiodiversity at different levels. The project attempted to reconcile the two views in developing frameworks for the determination of ‘best practice’

Analysis of markets for African leafy vegetables within Nairobi ant its environs and implications for on-farm conservation of biodiversity

African Leafy Vegetables (ALVs) are important sources of essential macro and micro-nutrients. In addition they offer a source of livelihood when marketed, and also contribute to crop biodiversity. Despite these positive aspects, only a few ALVs are grown, marketed and consumed in Kenya. This study analyses the ALV market in Nairobi and the neighbouring areas, highlighting the factors that enable or inhibit its development. Furthermore, the study determined different factors influencing inter- and intra-specific on-farm biodiversity, with a focus on the role of ALV market development

Diffuse versus square-well confining potentials in modelling AA@C60_{60} atoms

Attention: this version-$2$ of the manuscript differs from its previously uploaded version-$1$ (arXiv:1112.6158v1) and subsequently published in 2012 J. Phys. B \textbf{45} 105102 only by a removed typo in Eq.(2) of version-$1$; there was the erroneous factor "2" in both terms in the right-hand-side of the Eq.(2) of version-$1$. Now that the typo is removed, Eq.(2) is correct. A perceived advantage for the replacement of a discontinuous square-well pseudo-potential, which is often used by various researchers as an approximation to the actual C$_{60}$ cage potential in calculations of endohedral atoms $A$@C$_{60}$, by a more realistic diffuse potential is explored. The photoionization of endohedral H@C$_{60}$ and Xe@C$_{60}$ is chosen as the case study. The diffuse potential is modelled by a combination of two Woods-Saxon potentials. It is demonstrated that photoionization spectra of $A$@C$_{60}$ atoms are largely insensitive to the degree $\eta$ of diffuseness of the potential borders, in a reasonably broad range of $\eta$'s. Alternatively, these spectra are found to be insensitive to discontinuity of the square-well potential either. Both potentials result in practically identical calculated spectra. New numerical values for the set of square-well parameters, which lead to a better agreement between experimental and theoretical data for $A$@C$_{60}$ spectra, are recommended for future studies.Comment: 11 pages, 4 figure

Student Evaluation of Faculty Physicians: Gender Differences in Teaching Evaluations

Purpose: To investigate whether there is a difference in medical student teaching evaluations for male and female clinical physician faculty. Methods: The authors examined all teaching evaluations completed by clinical students at one North American medical school in the surgery, obstetrics and gynecology, pediatrics, and internal medicine clinical rotations from 2008 to 2012. The authors focused on how students rated physician faculty on their ?overall quality of teaching? using a 5-point response scale (1?=?Poor to 5?=?Excellent). Linear mixed-effects models provided estimated mean differences in evaluation outcomes by faculty gender. Results: There were 14,107 teaching evaluations of 965 physician faculty. Of these evaluations, 7688 (54%) were for male physician faculty and 6419 (46%) were for female physician faculty. Female physicians received significantly lower mean evaluation scores in all four rotations. The discrepancy was largest in the surgery rotation (males?=?4.23, females?=?4.01, p?=?0.003). Pediatrics showed the next greatest difference (males?=?4.44, females?=?4.29, p?=?0.009), followed by obstetrics and gynecology (males?=?4.38, females?=?4.26, p?=?0.026), and internal medicine (males?=?4.35, females?=?4.27, p?=?0.043). Conclusions: Female physicians received lower teaching evaluations in all four core clinical rotations. This comprehensive examination adds to the medical literature by illuminating subtle differences in evaluations based on physician gender, and provides further evidence of disparities for women in academic medicine.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140140/1/jwh.2015.5475.pd
